In order to solve the above-mentioned technical problems, as shown in fig. 1 to 3, an embodiment of the present invention provides an open bogie frame, which mainly includes a cross beam 10 and a side beam 20.
In this embodiment, the beam 10 includes a beam seat plate 11, the beam seat plate 11 is in a plate-like structure, the middle of the beam seat plate 11 is in a hollow structure, the hollow structure divides the beam seat plate 11 into a pair of transverse plates 111 and a pair of longitudinal plates 112 which are opposite to each other and enclose a shape similar to a "mouth", and the four corners of the beam seat plate 11 are provided with beam support plates 113 extending in the transverse direction of the beam 10.
It should be noted that, in this embodiment, both the "lateral direction" and the "longitudinal direction" are referred to with respect to the direction in which the bogie is mounted on the rail vehicle, and are the "longitudinal direction" along the running direction of the rail vehicle and the "lateral direction" along the width direction of the rail vehicle.
In this embodiment, the beam seat plate 11 is a monolithic plate structure, and may be formed into an integral structure with the beam support plate 113 by machining. Because the cross beam 10 is mainly of a plate-shaped structure, the weight is obviously reduced compared with the prior cross beam 10 adopting steel pipes.
In this embodiment, the side members 20 are in one-to-one correspondence with the cross member support plates 113, that is, four side members 20 are included, and each side member 20 is welded above the cross member support plate 113, thereby forming a frame form in which the four side members 20 are welded at four corners of the cross member seat plate 11. Specifically, each side member 20 includes an L-shaped stay 21 and a longitudinal seat plate 22, the L-shaped stay 21 includes a lateral stay 211 and a longitudinal stay 212 connected to the lateral stay 211, the lateral stay 211 is integrally formed with the longitudinal stay 212, the lateral stay 211 coincides with the extending direction of the cross member stay 113, and the longitudinal stay 212 extends toward a direction perpendicular to the cross member stay 113.

In this embodiment, the side beam 20 has an open i-beam structure, which provides a better operation space for welding the side beam 20 and the beam seat plate 11, and ensures the welding quality of the key weld.
In this embodiment, the side beam 20 and the cross beam 10 may be separately manufactured, and after the assembly welding of the side beam 20 is completed, the side beam is welded to the cross beam seat plate 11 of the cross beam 10, so that the welding efficiency is high, and the frame manufacturing efficiency is high.
To secure structural strength of the side sill 20, the transverse risers 23 are overlapped and welded with the longitudinal risers 24.
It will be appreciated that the transverse risers 23 and the longitudinal risers 24 extend in the vertical direction of the frame.
To ensure structural strength, the longitudinal saddle 22 is welded to the cross saddle 11. In addition, the length of the longitudinal seat pan 22 is smaller than the lengths of the longitudinal risers 24 and the longitudinal braces 212, so that a part of the longitudinal risers 24 are welded to the longitudinal seat pan 22 and another part are welded to the surface of the cross member seat pan 11, whereby the welding area of the side members 20 to the cross member seat pan 11 can be increased, thereby securing the stability after the welding of the side members 20 to the cross member 10.
In this embodiment, four L-shaped side members 20 are assembled and welded with a cross member 10 having a pair of cross plates 111 and a pair of longitudinal plates 112 to form a "well" -shaped frame structure.

The beam bottom plate 12 and the beam bottom plate 11 are welded by plates, so that the welding is convenient, and the quality of welding seams is easy to control.
